A source told the newspaper: “Louis is very much a part of the X Factor family.

“He’s a close friend of the show and would make a brilliant judge. Simon mentored One Direction and signed them to Syco Records, Now he’s looking after Louis’ solo career – which is going really well.

“Simon hopes the deal will be done in the next few days.”
